LIKE Alfredo Rosselli, Milan, Italy Application November 20, 1937, Serial No. 175,566 In Italy December 12, 1936 1 Claim.

The subject matter of this invention is a device for connecting and fastening the shoe of a rail with the underlying carrier of concrete or the like.

The apparatus of this kind, to be obtained from cast iron or cast steel, is shown by way of example in the annexed drawing.

Fig. 1 shows partly a front View and partly a cross section thereof.

Fig. 2 shows partly a longitudinal section and partly a side elevation.

Fig. 3 shows a plan view of a half thereof.

The device in the embodiment shown is formed with a number of ribs at right angles, say, four longitudinal main ribs or (the direction of which is perpendicular to the longitudinal axis of the rail) and three transverse ribs b which are perpendicular to the former.

The upper profile of the longitudinal ribs (1 has a slope of 1:20 in order that the same inclination may be given the rail.

The two transverse head ribs b which are provided at the bottom with holes 1 through which will pass the round bars g to connect the apparatus with the carrier of concrete are provided towards the outside of the apparatus with two horizontal ribs which are stiffened at the bottom by the extension of the longitudinal ribs a.

Above these two horizontal ribs opposite to the extension of the two longitudinal central ribs 0. there are provided the projections d which are necessary for receiving the bolts e and the small gripping plates h adapted for clamping the shoe of the rail 1' against the apparatus.

The heads 2 of the bolts 6 appear thus clamped within two deep and strong recesses with semicircular top opening towards the exterior and the small plates are wedged between the edges of the rail-shoe and its own seat which are also laterally opposed by opposite projections Z. provided on the two head ribs.

The apparatus is to be put into operation by immersion into the concrete during the casting of the carrier and the concrete must embed the same until it reaches the upper profile of the metallic ribs a so as to form with the latter the layingplane for the rail-shoe. The laying of the railshoe is to be made by interposition of an elastic cushion m.

Having now particularly described and ascertained the nature of my said invention and in 10 what manner the same is to be performed, I declare that what I claim is:

A tie plate for connecting the shoe of a rail to a carrier or tie of concrete or the like, comprising a unitary cast metal body including four standing longitudinal ribs having an upper profile inclined at about 1 to with the horizontal, and three spaced cross ribs perpendicular to said longitudinal ribs in the same general plane and having substantially the same vertical dimensions 2 as said longitudinal ribs, extensions on the two inner longitudinal ribs cooperating to form embracing means for securing vertical bolts and additional bracing elements provided with undercut projections cooperating with said embracing means for receiving said bolts and associated clamping plates adapted to connect the rail shoe with said tie plate by causing said shoe to rest on the upper inclined profile of said longitudinal ribs, said tie plate being adapted to have a resilient cushion member interposed between said upper inclined profile of the longitudinal ribs and said rail shoe, the lower portions of said cross ribs being formed with apertures for receiving connecting bars therethrough which serve to connect the entire tie plate intimately with the concrete carrier, while the ribs form cells therebetween adapted to be filled with the concrete of said carrier.
